摘要

采用溶胶凝胶法，以银氨离子为银源，原位合成了含Ag六方介孔硅（Ag-HMS）无机抗菌材料，探讨了其抗菌性能，并利用XRD、FT-IR、TG-DTA、UV-Vis、ESEM、EDS及N2的吸附/脱附等方法对材料进行了表征。结果表明，材料保持了良好的介孔结构和热稳定性，具有良好的紫外线吸收性能，银物种以骨架态和非骨架态形式存在并且分散均匀;相对于HMS，Ag-HMS材料脱模时的热化学过程、孔体积、介孔有序度、比表面积及粒子形貌均发生了显著改变。在抑菌实验中，Ag-HMS对枯草杆菌(B.subtilis)、大肠杆菌(E.coil)、芽孢杆菌(G.bacillus)及金黄色葡萄球菌(S.aureus)均显示出良好的抗菌性能，其中对枯草杆菌和大肠杆菌尤为显著，当Ag-HMS用量为1.00 mg·L-1，12 h后即可将两者彻底杀灭。

Abstract

Silver-modified hexagonal mesoporous silica (Ag-HMS) was in situ synthesized with the sol-gel method and by using ［Ag(NH3)2］+ as the silver source.The structure and properties were characterized by XRD

FT-IR

TG-DTA

UV-Vis

ESEM

EDS and N2 adsorption/desorption

and the antibacterial ability was investigated.The results indicated that Ag-HMS had favorable mesoporous structure

thermal stability and absorption ability of ultraviolet radiation

the silver species were evenly distributed in the material and existed in the form of framework/non-framework.As compared with HMS

Ag-HMS changed significantly in terms of demoulding thermochemical process

pore volume

mesoporous degree of orderliness

specific surface area

and particle shape.The results of antibacterial experiments showed that Ag-HMS had strong inhibition on B.subtilis

E.coil

G.bacillus and S.aureus.Especially for B.subtilis and E.coil

at the dose of Ag-HMS up to 1.00 mg·L-1

these two bacteria were entirely killed after incubation for 12 h.
